When using the DaskTaskManager with Slurm, the network interface configuration is primarily handled through Dask's distributed scheduler settings. Here's what you need to know: 1. By default, Dask will attempt to automatically detect the appropriate network interface. 2. You can explicitly specify the network interface using the

interface

parameter when configuring your DaskTaskManager. This corresponds to Dask's distributed scheduler configuration. Here's an example of how you can configure it:

python
from prefect_dask import DaskTaskManager

task_manager = DaskTaskManager(
    cluster_kwargs={
        "interface": "eth0"  # or your specific network interface
    }
)

To determine which network interfaces are available: 1. On your Slurm cluster nodes, you can use standard Linux commands:

bash
   ip addr show
   # or
   ifconfig

2. You can also use Python's

netifaces

library to programmatically check available interfaces:

python
   import netifaces
   available_interfaces = netifaces.interfaces()

If you're having trouble with automatic interface detection, common interfaces to try are: -

eth0

(standard ethernet interface) -

ib0

(InfiniBand interface, if available) -

bond0

(if using network bonding) For more detailed information about Dask's distributed networking configuration, you can refer to the Dask Distributed documentation. If you're experiencing specific networking issues or need more targeted help, could you share more details about your Slurm cluster setup and any particular problems you're encountering?
